I've created a very simple Copilot with one SharePoint site as its knowledge data source.
The site has top level document libraries with PDFs in.
I've followed all the documentation to set up authentication, trying multiple times...
- App Registration in Azure
- Redirect URI set up
- API permissions set up and admin consent granted (User.Read, Sites.Read.All, Files.Read.All, openid, profile)
- Exposed API (Test.Read)
- Added ClientID and Secret for Azure Active Directory V2 in Copilot security settings
- Added these Scopes in Copilot settings - profile openid Sites.Read.All Files.Read.All
I've published the Copilot numerous times. No matter what question I ask about the PDFs (they're HR policies), I get a response like "I apologize, but I’m unable to provide information about your specific policies as I don’t have access to that information. It would be best to consult your organization’s official documentation or contact the appropriate department for details on your policies."
I've doubled checked no authentication error appears in the Conversational Boosting topic, which it doesn't. I'm all out of options. Can anyone help?


Thanks
